Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164146, here are decompositions:

29 + 164117 = 164146
53 + 164093 = 164146
89 + 164057 = 164146
107 + 164039 = 164146
149 + 163997 = 164146
167 + 163979 = 164146
173 + 163973 = 164146
263 + 163883 = 164146

Showing the first eight; more decompositions exist.
